I was writing a nonfiction children's book on puffins for an educational publisher, and I visited Handa Island, a tiny island off the northwest coast of Scotland, as part of my research. A small ferry dropped my husband and me on a beach, and we walked (and climbed) for close to an hour across the island to get to where the puffins hang out. We were rewarded with this amazing view of Great Stack, which is home to puffins, razorbills, guillemots, kittiwakes, and fulmars during the nesting season. All the tiny black dots along the rock ledges are vast numbers of seabirds. (The second photo shows how packed together they are.) It was a great privilege to be able to visit their world.
